I was nervous my daughter wouldn't like these after using another type of binkie for the first 9 months of her life. But after she started putting the entire thing in her mouth, I needed to find something bigger she couldn't do that with. She LOVES these! and I love that they're big enough she can't get the whole thing in her mouth. I also love that they are one solid piece so they don't have any crevices to get gunk stuck in!
